Astros general manager Jeff Luhnow did not rule out another addition to his club before it convenes in West Palm Beach, Fla., but he acknowledged it would “most likely” be non-roster invitees who compete for jobs in spring training.

“We’re starting from a pretty good spot where we have a lot of good options for our roster and a lot of good options who aren’t even going to make our team,” Luhnow said Wednesday. “Whoever we get, if you sign them to a guaranteed contract, they have to be certainly better than what your internal options are.”

The Astros have one spot open on their 40-man roster, but already face a sizable roster crunch within its outfield and bench. Jake Marisnick will be out of options by May and Tony Kemp will begin the season with no options available. Kyle Tucker, the organization’s No. 1 position player prospect, and Myles Straw are already on the 40-man roster, too.

Their infield is entrenched and, ostensibly, a spot in the bullpen will be solved once the competition for the fifth starter role is complete. Luhnow said the organization must stay ready, too, for the non-waiver trade deadline in July, should in-season help be required.

“We talked about leaving stuff in the tank, whether it’s money or prospects, to make some deals during the season or even before the season if it presents itself,” Luhnow said. “We’re not going to rest on our hands, but we certainly like the team we have and we think we have a pretty good chance of accomplishing our goals.”
